Electric Fan(s)? - Telecommbrkr - 01-19-2009
Has anyone done this? Any benefit? If so, how does one go about setting up a thermo controlled fan switch/actuator? I would like to do this to gain room for intercooler installation....

Its a total waste of time.
The HP and economy difference is almost nonexistent. When the radiator is cool the fan is freewheeling and taking almost no power. The fan doesn't even start to lock up until 164*f air temperature (about 90*c coolant). You would need to be frequently driving in the mountains or towing a trailer for an electric fan to save any money.
If you want reliability stick with the clutch fan. It has 1 failure point- The clutch. Electric fans have 5 failure points- Motor, relay, temperature sensor/switch, fuse and many electrical connections.
If you want more space move your radiator back about 1", there is plenty of dead space between it and the fan. You can also switch to the solid mounted 240D fan. That will get rid of the clutch and move the fan back another 2".
